Abstract
Although there is considerable evidence that efforts to teach economic concepts to elementary school children are increasing, little research is being done at this level. William Walstad's article is, then, one of those rare pieces that reports the results of a controlled study in the elementary grades. In addition, it includes a discussion of research design and statistical techniques, and considers some of the problems one encounters in this type of research (such as problems in parameter estimation). The author measured the effects of a teacher in-service program that provided instruction in economics as applied to the Unified Sciences and Mathematics for Elementary School program. The new Test of Economic Literacy was administered to the teachers, while their pupils took the Test of Elementary Economics. Control groups were also tested. Pupil attitudes toward economics were measured, and it was found that achievement in economics had a direct influence on attitude toward economics. Walstad concludes that “teachers and students gain substantial benefits from the in-service program in practical economic problem solving.”
